The new compounds [Ni(L₁)][Ni(L₁)Sn₂S₆]_n·2H₂O (I) and [Ni(L₂)]₂[Sn₂S₆]·4H₂O (II) containing the macrocyclic ligands L₁ (L₁ = 1,8‐dimethyl‐1,3,6,8,10,13‐hexaazacyclotetradecane) and L₂ (L₂ = 1,8‐diethyl‐1,3,6,8,10,13‐hexaazacyclotetradecane) were prepared at room temperature by overlaying an aqueous solution of Na₄SnS₄·14H₂O with the [Ni(L₁)](ClO₄)₂ complex dissolved in CH₃CN (I) or by overlaying a solution of the [Ni(L₂)](ClO₄)₂ complex dissolved in DMSO with an aqueous solution of Na₄SnS₄·14H₂O (II). The slow interdiffusion of the two solvents guarantees supersaturation in the interface region of the solvents so that crystallization of the compounds occurs. In the structure of I one Ni²⁺ cation has bonds to S^2– anions of the thiostannate anion thus generating chains along [100]. This cation is in an octahedral environment of four N atoms of L₁ and two S atoms of the [Sn₂S₆]^4– anion. The second [Ni(L₁)]²⁺ complex exhibits a square‐planar coordination geometry. These [Ni(L₁)]²⁺ complexes and water molecules are located between the chains. In the structure of II isolated [Sn₂S₆]^4– anions and [Ni(L₂)]²⁺ cations are observed. The Ni²⁺ cations are fourfold coordinated by N atoms of the L₂ ligand and feature also a square planar environment.
